IMPROVED MACHINEl FOR BENDING HORSESHOES.

Specification forming part of Letters Patent No. 55,042. dated May 29,1866.

To all whom it may concern: A

Be it known that LHAZEN .I BATGHELDER, of Boston, of the county ofSuffolk and State of Massachusetts, have invented a new and useful orImproved Machine for Bending Iron for its Conversion into a Horseshoe;and I do hereby declare the same to be fully described in the followingspecilication, and represented in the accompanying drawings, of which-Figure lis a top view, and Fig. 2 a longitudinal and vertical section ofsuch machine.

In the said drawings A denotes a former, which is arranged on abed-plate, G, and shaped to correspond with the interior edge of ahorseshoe. This former is made on or afxed to a pitman or slide,B,.provided with a toothed rack or series of teeth, U, to en gage with agear, I). Such gear is duly supported by a shaft, E, sustained instandards b b, and has a lever, F, by which itmay be revolved so as toimpart to the pitman or slide and the former A their forward andbackward movements.

In advance of the said former and on the bed-plate G are two bending orcurved levers, H H, which when in use turn horizontally 011 fulcra a a,projecting upward from'the said plate. These levers, by cooperatingwith-the former A, serve to bend a horseshoe-blank or metal bar aroundthe edge ofthe said former, so as to impart to such bar the form ot' ahorseshoe.

The shorter arms of the levers, when such levers are open or inpositions to receive a blank, rest against abutments or adjustable stopsc c, arranged as represen ted. The longer arms d d of the levers arecurved toward each other, so that while the blank is iuthe act of beingforced against them by the former A the levers may be made to turn ontheir fulcra in a manner to cause their longer arms to graduallyapproach one another in a manner to set the horseshoe-blank in a line atits quarters and at the heels, and cause it to conform to the shape ofthe forming-edge of the part A.

There may be friction-rollers ce in the arms of the bending-levers, andthere may also be a spring, f, to each bendin g-lever, the said springbeing so applied to it and the bed-plate as to force open the levers orpress them into their proper positions for the reception of a blank.which, prior to beingbent,is to be placed against the extreme ends ofthe longer arms of the levers, and so that the formel-A during itsadvance may first touch the blank at its middle. For this purpose oneend of the blank may be pressed against a stop, g, fixed to thebed-plate.

For separating the blank from the former A, I employ two dischargers, h11 which are stationary abutments, against which the heels of the blankare drawn by the pitman or slide B while it is in the act of beingretracted and after the blank may have been drawn away from the levers.The abutments spring the blank off the former A, the elasticity of thequarters afterward serving to restore the blank to, or about to, itsproper shape.

In order to prevent the blank from curling 01 being bent laterally orupward or downward at its toe during the process of bending such blank,there are two jaws, ik, projecting from the front end of the former A.These jaws embrace the blank at its middle and on opposite faces ot'it;or, in other words, the blank enters between the said jaws, and theyprevent it from being bent either up or down.

I make no claim to the invention of any mechanism or combination ofparts described in the patent of William Gibson, dated December 27,1843.

I claim- 1. -The benders H H, made and arranged in combination with thespringf, in manner and so as to operate with the former A, substantiallyas described.

2. The combination and arrangement of the jaws t 7c with the former A,combined and to operate with the spring bending-levers H H,substantially in manner as described.

3. The combination as well as the arrangement of the dischargers h hwith the formerA and the bending-levers H H.
